WIRE-=TWISTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 399,856, dated March19, 1889.

Application filed January 17, 1889. Serial No. 296,589. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN XV. JISENHART, a citizen of the United States,residing at York, in the county of York and State of Pennsylvania, haveinvented certain new and useful Improvements in iVire lwisting Tools orMachines, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention has for its objects to provide a machine by means ofwhich the adjoining ends of two wires may be rapidly and securelytwisted, so as to firmly and neatly join the same, as more fullyhereinafter specitied.

The above-mentioned objects I attain by the means illustrated in theaccompanying drawings, in which Figure l representsafront elevation ofmy improved machine complete. Fig. 2 repre sents a vertical sectionalview thereof. Fig. 3 represents a similar view taken in a plane at rightangles to Fig. 1. Fig. 4: represents a detached view of a guide andbending-plate employed in connection with the machine and forming partthereof. Fig. 5 represents a detached View of a bending-plate, one ofwhich is attached to each of the twisting-wheels. Fig. 6 represents adetached elevation of one of the twisting-wheels and its attached disk.Fig.7 represents a front elevation of one of the twisting-wheelsdetached. Fig. 8 represents a detached perspective view of adetentspring for holding the gearing of the machine, as more fullyhereinafter set forth. Fig. 9 represents a view of the wires, showingtheir adjoining ends twisted; and Fig. 10, a similar view of the wires,showing the ends completely twisted, trimmed, and finished.

Referring to the drawings, the letter A indicates the frame of themachine, which is formed with a suitable base, B, upon which it stands.The front of said frame is provided with a circular recess, 0, in whichis located a beveled cog-wheel, D, which turns upon a.

screw-threaded bolt, E, by means of which it is fastened to the frame.The said wheel is provided with a suitable crank, F, by means of whichit may be turned by hand. Diametrically opposite the said crank thefront face of the wheel near its edge is provided with a recess, a, intowhich a spring.- detent, G, is adapted to project and arrest the motionof the wheel and hold the. gearing of the machine, as more fullyhereinafter explained. The wheel D gearswith a beveled cog-pinion, H,which is secured to the lower portion of a vertical spindle, l,journaled in suitable bearings in the frame. The upper end of saidspindle projects above its upper bearing and has secured to it ahorizontal miter or beveled cog-wheel, K, which intergears with twovertical miter or beveled cog-wheels, L M, at diametrically-oppositesides of the said wheel The twisting cog-wheels L M have open centersand on their plain faces are provided with short central bosses N, whichfit and are adapted to rotate in bearings in the vertical standards P,rising from the top of the frame at opposite sides thereof, as shown inFigs. 1, 2, and 3 of the drawings. The said wheels L M have fastened totheir bosses the confining-disks R, by which they are held in theirbearings, but permitted to rotate freely therein. The adjacent faces ofthe said wheels L M in the space between the annular row of cogs havesecured to them the rotating wiretwisting disks T by means of screws orotherwise, and to the outer portions of the standards P opposite thebearings therein are secured by means of screws or otherwise stationarywire-twisting plates S, which serve also as guides to the wires.

The stationary twisting-plates S, the twisting-wheels L M, thetwisting-disks T, and the confining-plates R, above mentioned, aredivided from their peripheries to their centers, as indicated, so thatthe wires with their ends placed together, as shown in Fig. 2 of thedrawings, may be centered in the angle of the division-slots of thestationary twisting plates and held thereby while being twisted.

The operation of my invention will be fully understood in connectionwith the foregoing description, and is as follows:

The wires are placed together at their ends and inserted into thedivision-slots of the respective twisting disks and plates and centeredtherein, the division-slots being of such width that the wires arecompelled to assume a position one above the other as they pass into thesame. The gearing is then set in motion by turning the crank, rotatingthe twisting Wheels and disks in opposite directions. These twist thewires at three pointsthat is, at a between the two twisting-disks and atb b at each side of the same between said disks and the stationarytwisting-plates S, secured to the standards of the frame. The stationarytwisting-plates S for convenience may be provided with guiding-ears a,as shown in Fig. 4 of the drawings.

It is evident that the confining-disks B may be made integral with thecog-wheels and that the disks S may be made integral with the framewithout departing from the spirit of my invention.

Having thus fully described my invention, whatI claim, and desire tosecure by Letters Patent, is-

1. In a machine for joining the ends of wires, the combination of twoouter stationary twisting-plates radially slotted for the reception ofthe wires, two intermediate twistingwheels carrying twisting-disks, andmeans for rotating the said intermediate twisting-wheels in oppositedirections, as and for the purpose set forth.

2. In a machine for twisting the ends of wires and joining themtogether, the combi nation of two outer stationary twisting-plates, twointermediate twisting-wheels, and an intermediate bevel cog-wheelengaging the said twisting-wheels and adapted to rotate them in oppositedirections, substantially as and for the purpose specified.

3. The combination of a frame, outer stationary slotted plates, S S,carried by the frame, intermediate twisting-wheels, L M, provided withbosses N, these wheels being journaled inv the frame, rotating twistingslotted disks T upon the adjacent faces of the said twistingwheels, abevel cog-wheel, K, engaging the said twisting-wheels and adapted torotate them in opposite directions, a bevel-pinion, H, secured upon theshaft of the said wheel K, and a driving bevel gear-wheel, D, engagingthis latter wheel, all arranged substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
